I've got low expectations for this game, the first one was bad besides zombies
The first Black Ops was a hit. For a very long time, there have been over 1 million people playing it (shown in people online). However, ever since MW3 came out. The number reduced to about 500 K people.
From the way it looks, Black Ops 2, will be the biggest hit.
It has 8 player zombies, Spec Ops, Survival, and Infected. It will have crazy guns and some of the guns in MW3.
This could be the biggest hit, especially when there is a possibility that the multiplayer maps could be zombies maps. That could mean Nuketown zombies for 8 people.
